Android NDK中的陀螺仪和磁场传感器事件

查看传感器头文件：

ANDROID-NDK-ROOT-DIR/platforms/android-/arch-arm/usr/include/android/sensor.h

typedef struct ASensorVector {

union {

float v[3];

struct {

float x;

float y;

float z;

};

struct {

float azimuth;

float pitch;

float roll;

};

};

int8_t status;

uint8_t reserved[3];

} ASensorVector;

typedef struct ASensorEvent {

int32_t version; /* sizeof(struct ASensorEvent) */

int32_t sensor;

int32_t type;

int32_t reserved0;

int64_t timestamp;

union {

float data[16];

ASensorVector vector;

ASensorVector acceleration;

ASensorVector magnetic;

float temperature;

float distance;

float light;

float pressure;

};

int32_t reserved1[4];

} ASensorEvent;

对了，我发现了这个例子：
